------------------------------------------------------------
[~twalthr] [~fhueske] any thought on this JIRA? my feeling is that this is a
problem but not so much critical as it doesn't break the system itself. But I
myself found out about this in the hard way so it does affect debuggability of
flink users/developers.
However in order to fix this there's going to be a huge amount of changes on
many test files. So would like to get your opinions first before I dive into
the actual changes.

> Key: FLINK-11569
> URL: https://issues.apache.org/jira/browse/FLINK-11569
> Project: Flink
> Issue Type: Bug
> Components: Type Serialization System
> Reporter: Rong Rong
> Assignee: Rong Rong
> Priority: Major
>
> Seems like the "toString" method for Row type is only concatenating all
> fields using COMMA ",". However it does not wrap the entire Row in some type
> of encapsulation, for example "()". This results in nested Row being
> serialized as if they are all in one level.
> For example:
> {code:java}
> Row.of("a", 1, Row.of("b", 2))
> {code}
> is printed out as
> {code:java}
> "a",1,"b",2
> {code}
> Problematic piece of code can be found here:
